Umsele
Imigaqo nemiyalelo yesizwe neyengingqi malunga nomhlaba ogqunyweImibhobho ye-PEkufuneka kulandelwe ngexesha lokwakhiwa komsele ofunekayo. Umsele kufuneka uvumele zonke iindawo zombhobho ukuba zibe kubunzulu obukhuselekileyo kwiqabaka kwaye zibe nobubanzi obaneleyo.
Ububanzi bomsele
Xa kujongwa iprojekthi kunye nefuthe elongezelelekileyo kwimibhobho esuka emhlabeni, ububanzi bomsele kufuneka bube mxinwa kangangoko kunokwenzeka.
Uluhlu olucebisa ububanzi bomsele. La maxabiso ahambelana nemigaqo yokuba ububanzi bomsele bufanele bube mxinwa kangangoko ukuze kuncitshiswe imithwalo yangaphandle kunye neendleko zokufakela, ngelixa kunika nendawo eyaneleyo yokubonelela ngoxinzelelo oluchaziweyo.
Ububanzi bomsele osetyenziswayo buya kuchaphazela imeko yomhlaba, iinkqubo zokudibanisa, kunye nokuba iijoyinti zenziwe na kumsele.
Ububanzi bomsele obucetyiswayo

PhiImibhobho ye-PExa zifakelwe nezinye iinkonzo kwiimeko eziqhelekileyo zomsele, ububanzi bomsele bungachazwa yimigaqo yegunya lendawo ukuze kuvunyelwe imisebenzi yolondolozo kamva.
Ubunzulu bomsele
AphoImibhobho ye-PEumgca webanga awuchazwanga, isigqubuthelo esingaphezulu kwemibhobho ye-PE kufuneka sibekwe ukuze kubekho ukhuseleko olufanelekileyo kwimithwalo yangaphandle, umonakalo womntu wesithathu, kunye nokuhamba kwezithuthi zokwakha.
Apho kunokwenzeka, imibhobho kufuneka ifakwe phantsi kweemeko zobunzulu obuphantsi kwaye, njengesikhokelo, amaxabiso adweliswe ngezantsi kufuneka amkelwe.

Ufakelo Olungaphezulu Komhlaba
Iipayipi ze-CHUANGRONG PE zingafakelwa ngaphezulu komhlaba ukuze zisetyenziswe uxinzelelo kunye nokungasebenzisi uxinzelelo kuzo zombini iimeko zokuvezwa ngqo kunye neemeko ezikhuselekileyo. Iipayipi ze-PE ezimnyama zingasetyenziswa kwiimeko zokuvezwa ngqo elangeni ngaphandle kokhuseleko olongezelelweyo. Apho iipayipi ze-PE ezinemibala engaphandle komnyama zisetyenziswa kwiimeko zokuvezwa, ke iipayipi kufuneka zikhuselwe elangeni. Apho iipayipi ze-PE zifakwe kwiimeko zokuvezwa ngqo, ke ubushushu obunyukileyo bezinto ze-PE ngenxa yokuvezwa kufuneka buthathelwe ingqalelo ekumiseni umlinganiselo woxinzelelo olusebenzayo lweepayipi ze-PE. Iimeko zokwakheka kobushushu bendawo ezifana nokuba kufutshane nemigca yomphunga, ii-radiator, okanye ii-exhaust stacks kufuneka ziphetshwe ngaphandle kokuba iipayipi ze-PE zikhuselwe ngokufanelekileyo. Apho kusetyenziswa izinto ezishiyekayo, ezi kufuneka zilungele ukusetyenziswa kokuvezwa.
Izinto zokulala kunye nokuzalisa umva
Umgangatho womsele ombiweyo kufuneka uchetywe ngokulinganayo, kwaye ungabi namatye, nezinto eziqinileyo. Izinto zokulala ezisetyenziswa kwimisele nakwiindawo ezibiyelweyo mazibe zezinye zezi zilandelayo:
1. Isanti okanye umhlaba, ongenamatye angaphezu kwe-15 mm, kunye nazo naziphi na iziqwenga zodongwe eziqinileyo ezingaphezu kwe-75 mm ngobukhulu.
2. Ilitye elityumkileyo, ilitye elirhabaxa, okanye izinto ezilinganisiweyo ngokulinganayo ezinobukhulu obuphezulu be-15 mm.
3. Izinto ezigrunjiweyo ezingenamatye okanye izinto zemifuno.
4. Amaqhuma odongwe anokuncitshiswa abe ngaphantsi kwe-75 mm ngobukhulu.
Kwinkoliso yezicelo zemibhobho ye-PE, ubuncinane i-75mm yezinto zokulala ziyasetyenziswa kwimisele nakwiindawo ezingqonge umhlaba. Kwimigodi edwaleni, ubunzulu bebhedi obuyi-150 mm bungafuneka.
Inxalenye eseleyo yomsele, okanye ugcwaliso lwe-embankment ingenziwa ngezinto zendalo eziye zambiwa ngaphambili.
Ezi zinto mazingabi namatye amakhulu, izinto zemifuno, nezinto ezingcolileyo, kwaye zonke izinto kufuneka zibe nobukhulu obukhulu bamasuntswana angaphantsi kwama-75 mm.
Apho imibhobho ye-PE ifakelwe kwiindawo ezinemithwalo ephezulu yangaphandle, ke izinto zokugcwalisa umva kufuneka zibe semgangathweni ofanayo nezinto zokulala kunye nezinto zokugquma.
Iibhloko zokuTshixa kunye nokuThintela imibhobho
Iibhloko zokutyhala ziyafuneka kwiipayipi ze-CHUANGRONG PE xa kusetyenzwa uxinzelelo apho amalungu angamelani nemithwalo emide. Iibhloko zokutyhala mazibonelelwe xa kukho utshintsho kwicala.
Apho kusetyenziswa iibhloko zekhonkrithi, iindawo zoqhagamshelwano phakathi kombhobho we-PE, okanye i-fitting kunye ne-thrust block kufuneka zikhuselwe ukuthintela ukurhawuzelelwa kwe-PE. I-rubber okanye i-malthoid sheeting ingasetyenziselwa le njongo.
Zonke izinto ezifakelwayo kunye nezinto ezinzima ezifana neevalvu zesinyithi eziphosiweyo kufuneka zixhaswe ukuze kuthintelwe ukulayishwa kwenqaku kwizinto ze-PE. Ukongeza, apho kusetyenziswa iivalvu, imithwalo ye-torque evela kwimisebenzi yokuvula/yokuvala kufuneka imelane neenkxaso zebhloko.
Ukugoba kweepayipi ze-PE
Zonke iipayipi ze-PE ezifakelwe kwi-alignment egobileyo kufuneka zitsalwe ngokulinganayo kulo lonke ubude begophe, kungabi ngaphezulu kwecandelo elifutshane. Oku kunokukhokelela ekuqhekekeni kobubanzi obuncinci, kunye/okanye iipayipi zodonga ezibhityileyo.
Imibhobho ye-PE emikhulu enobubanzi obuyi-450mm nangaphezulu kufuneka idityaniswe, ize itsalwe ngokulinganayo kwiradiyumu efunekayo. Irediyasi egobileyo evumelekileyo yombhobho we-HDPE inokufumaneka.
Ukubeka umqolo kwakhona kunye nomsele ongavulwanga
Iipayipi ezikhoyo zingahlaziywa ngokufaka iipayipi ze-CHUANGRONG PE kwiipayipi ezindala. Iipayipi zokufaka zinokutsalwa kwindawo yazo ngee-winch zoomatshini. Ukuphinda ufake iipayipi ngeepayipi ze-PE kubonelela ngesakhiwo esikwaziyo ukumelana noxinzelelo lwangaphakathi okanye umthwalo wangaphandle ngaphandle kokuxhomekeka kumandla aseleyo ezinto zokuqala zepayipi ezonakaliswe yimeko.
Iipayipi ze-PE zifuna imisele yokungena neyokuphuma emfutshane ukuze ilungele irediyasi yombhobho we-PE ukuze ingene kumbhobho okhoyo, kunye nendibano ye-winch esetyenziselwa ukutsala i-PE liner ecaleni kombhobho. Irediyasi encinci yokugoba yombhobho we-PE ingabalwa njengoko kuchaziwe phantsi kwePipeline Curvature yencwadana.
Iipayipi ze-PE zingasetyenziswa nakwiiprojekthi zemisele engeyoyembiwayo, ezifana ne-Horizontal Directional Drilling (HDD). Ezinye zeendlela zokuqala zokusetyenziswa kweepayipi ze-PE ezinobubanzi obukhulu ekubholeni kwicala elithile zazikukusebenzisa iindlela zokunqumla umlambo. Iipayipi ze-PE zifanelekile kwezi zinto ngenxa yokunyamezela kwayo ukukrwela kunye nenkqubo yokudibanisa edibeneyo enika i-joint yezinga lokuvuza elinoyilo olulinganayo nolo lombhobho.
Ukuza kuthi ga ngoku, abenzi bokugrumba abakhokelayo bafake umbhobho we-PE kwizixhobo zombane, amanzi, kunye nemibhobho yamanzi amdaka; imibhobho yonxibelelwano; imibhobho yombane; kunye nemigca eyahlukeneyo yeekhemikhali.
Ezi projekthi azibandakanyi nje kuphela ukuwela imilambo kodwa kwaneendlela zokuwela iindlela ezinkulu kunye neendlela eziya kwiindawo eziphuhlisiweyo ukuze zingaphazamisi izitalato, iindlela zokungena, kunye neengcango zoshishino.
Ukulungisa nokugcina
Ngokweengozi ezahlukeneyo, kukho iintlobo ngeentlobo zobuchwepheshe bokulungisa onokukhetha kuzo. Ukulungiswa kungenziwa kumbhobho omncinci ngokuvula indawo eyaneleyo yomsele kunye nokusika isiphene. Buyisela icandelo elonakeleyo ngecandelo elitsha lombhobho.
Ukulungisa umbhobho omkhulu obanzi kungenziwa ngesiqwenga sespool esijijekileyo. Icandelo elonakeleyo liyasuswa. Okulandelayo, umatshini wokudibanisa i-butt uthotyelwa emseleni. Uqhagamshelo olujijekileyo ludityaniswe kwisiphelo ngasinye esivulekileyo, kwaye indibano yespool ejijekileyo ibotshelelwa endaweni yayo. Ispool ejijekileyo kufuneka yenziwe ngokuchanekileyo ukuze ilingane nomsantsa ophumayo kumbhobho.
